CVE-2018-1131GHSA-qqfc-m9hc-pqv3

What to do

Partial vendor fix. Follow the primary source's mitigation guidance and check back for a fix.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Infinispan permits improper deserialization of trusted data via XML and JSON transcoders under certain server configurations. A user with authenticated access to the server could send a malicious object to a cache configured to accept certain types of objects, achieving code execution and possible further attacks. Versions 9.0.3.Final, 9.1.7.Final, 8.2.10.Final, 9.2.2.Final, 9.3.0.Alpha1 are believed to be affected.

# Patch Next advisory brief: CVE-2018-1131

Advisory: Deserialization of Untrusted Data in Infinispan
IDs: CVE-2018-1131, GHSA-qqfc-m9hc-pqv3
Record: https://patchnext.com/advisories/cve-2018-1131 (revision 1, source checked 26 Oct 2026, 16:00 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: org.infinispan:infinispan-core 9.3.1.Final. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.infinispan:infinispan-core: affected >= 8.2.10.Final, <= 8.2.10.Final; >= 9.0.3.Final, <= 9.0.3.Final; >= 9.1.7.Final, <= 9.1.7.Final; >= 9.2.2.Final, <= 9.2.2.Final; >= 9.3.0.Alpha1, <= 9.3.0.Alpha1; fixed in 9.3.1.Final

## Suggested inspection (read-only)
- Maven org.infinispan:infinispan-core: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.infinispan:infinispan-core.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
